I'm so sorry to hear about your father.
The original docs I went to see said I had 18 months to live with treatment, but that I could die at any moment. I went to the Masonic Cancer Clinic in Minneapolis, MN. I met with Dr. Edward Greeno. He let me know of a clinical trial for which I chose.
I had my colon resected on August 13, 2004
I had my liver resected on Sept 13, 2004 and had an HAI pump inserted. I used Irinotecan for systemic treatment and had FUDR in my HAI pump.
If you live in the US, I would suggest you visit one of these hospitals. I got my umpteenth opinion and am glad I did.
